This request is for market research purposes and is not a solicitation (Request for Proposal or Request for Quotations) or a promise to issue a solicitation in the future. The purpose of this RFI is to identify potential sources capable of providing the services currently performed at the Low Background Infrared (LBIR) facility at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD. The Air Force Metrology and Calibration Program (AFMETCAL) is the executing agent for the Missile Defense Agency (MDA) for this facility. This action is intended to be a short-term bridge contract to ensure continuity of critical services while the Government finalizes the acquisition strategy for a long-term, competitive follow-on contract. The anticipated period of performance for this bridge action will consist of six (6) one-month options, to be exercised as needed. Currently, there are no funds available for this acquisition. The LBIR Facility provides the infrared user community with a calibration base that includes both spectral and broadband measurements in a 20 K background environment. The facility is used for the spectral calibration of low-background infrared detectors, characterization of optical components, and cryogenic transfer radiometers used to evaluate highly collimated infrared sources. A potential offeror must have the immediate capability and expertise to perform these highly specialized services without a break in service or a lengthy ramp-up period. The draft statement of work is attached and it contains more detailed requirements. This synopsis is for planning purposes only and is NOT to be construed as a commitment by the Government. All costs associated with responding to this RFI will be solely at the responding partys expense. All information received in response to this RFI that is marked PROPRIETARY will be handled accordingly.
